STINKY TOY

I found the Sholai in the refugee camp, Masha taught me the language. She told me to go find the other guys. When I found the other guys, I tried talking to them but they act like i can't talk to them. I can talk to the ones in the Refugee Camp, but not the ones in the Wooded Valley. I checked a guide and it said i should be able to talk with them, what is the problem?
